This video is very much useful, but I am in preliminary stage of learning on DEM and it's objectives and hence, I mean I do need all process in DEM, but gradually trying to learning

Sir you put in map algebra (Flow account > 20,000) ? Is there any relationship or formula for it? Kindly guide

Hello, thanks for useful video, what is the different between using Hydrology in arc tools box and using Arc hydro extension and which one is better.
@GeoSpatialTutorials
@GeoSpatialTutorials 7 лет назад
Arc Hydro tools is better. It has few tools in addition. However best is when you use them together. ArcHydro is more useful while using for HEC software

I don't have this ArcHydro tools extension. What do I have to do to get this extension? I'm using ArcMap 10.2.2

Very helpful. Would like to know how you can use spatial analyst tools to do the same

You can use Hydrology option in Spatial analyst. But all the features are not available there

how did you get the flow accumulation to run so quickly? What type of machine are you working on? The flow accumulation process is taking several hours, and I've read else ware that it sometimes takes days. But your flow accumulation took 3 minutes???? Any suggestions? Thanks

Its a normal 2GB RAM. In any angle it should not take hours. May be some installation issue

Hi. Thanks for this nice tutorial. I have one question. When i overlaid the result with google earth, somehow the stream line did not represent the actual shape as it should be. The curve line of the stream not same as the google earth image. What is your suggestion? is it because of the simplification? thank you
@faisalrz87
@faisalrz87 7 лет назад
and i also find out that the stream a bit shifted on some part of the whole stream network
@GeoSpatialTutorials
@GeoSpatialTutorials 7 лет назад
It doesn't match perfectly because, DEM has square pixels. The shifted because network may because of some projection issue. You can do spatial adjustment as shown in other video in the tutorial
